Wood grain powder coating uses heat transfer technology to transfer patterns such as wood grain to powder coating through transfer paper. By adjusting the formula of powder coating, the ink on transfer paper can easily penetrate into the coating. At the same time, in the transfer process, the glue transfer is not fuzzy, no offset, and vacuum transfer is not sticky. Heat transfer powder can be widely used in the coating of aluminum alloy doors and windows, indoor metal furniture, automobiles, etc.
